Liver RNA-seq of gilthead seabream (Sparus aurata) submitted to different aquaculture challenges

Project description:Fish in aquaculture farms frequently face unfavarouble husbandry conditions and other unpredictable situations, which are sometimes part of routine procedures. However, managing stress originated from these situations is crucial to ensure the sustainability of the production. When fish is exposed to prolonged stress, and overload of the physiological systems can occur and the fish may no longer be able to adapt and restore homeostasis, and this can impair the animal performance, such as growth and immunity, and consequently fish welfare. In this study the genes and gene families responsible for the molecular stress response to different challenges in gilthead seabream was assessed. Gilthead seabream adults were exposed to overcrowding, net-handling and hypoxia, in separate trials, each against a control group. Overcrowding and net-handling trials lasted for a month and half (chronic stress) and hypoxia for 48h (acute stress). The liver was the chosen organ for this transcriptomics analysis as this plays a crucial role in stress adaptation. The characterization of stress adaptation mechanisms provides valuable knowledge for the future selective breeding of more resilient commercial species that can thrive under changing conditions and adapt well to life in captivity, while ensuring high welfare standards.

Fish Processing and Digestion Affect Parvalbumins Detectability in Gilthead Seabream and European Seabass.

Project description:Consumption of aquatic food, including fish, accounts for 17% of animal protein intake. However, fish consumption might also result in several side-effects such as sneezing, swelling and anaphylaxis in sensitized consumers. Fish allergy is an immune reaction to allergenic proteins in the fish muscle, for instance parvalbumin (PV), considered the major fish allergen. In this study, we characterize PV in two economically important fish species for southern European aquaculture, namely gilthead seabream and European seabass, to understand its stability during in vitro digestion and fish processing. This information is crucial for future studies on the allergenicity of processed fish products. PVs were extracted from fish muscles, identified by mass spectrometry (MS), and detected by sandwich enzyme-linked immunosorbent assay (ELISA) after simulated digestion and various food processing treatments. Secondary structures were determined by circular dichroism (CD) after purification by anion exchange and gel filtration chromatography. In both species, PVs presented as α-helical and β-sheet structures, at room temperature, were shown to unfold at boiling temperatures. In European seabass, PV detectability decreased during the simulated digestion and after 240 min (intestinal phase) no detection was observed, while steaming showed a decrease (p < 0.05) in PVs detectability in comparison to raw muscle samples, for both species. Additionally, freezing (−20 °C) for up to 12 months continued to reduce the detectability of PV in tested processing techniques. We concluded that PVs from both species are susceptible to digestion and processing techniques such as steaming and freezing. Our study obtained preliminary results for further research on the allergenic potential of PV after digestion and processing.

Factors Driving Bacterial Microbiota of Eggs from Commercial Hatcheries of European Seabass and Gilthead Seabream.

Project description:A comprehensive understanding of how bacterial community abundance changes in fishes during their lifecycle and the role of the microbiota on health and production is still lacking. From this perspective, the egg bacterial communities of two commercially farmed species, the European seabass (Dicentrarchus labrax) and the gilthead seabream (Sparus aurata), from different aquaculture sites were compared, and the potential effect of broodstock water microbiota and disinfectants on the egg microbiota was evaluated. Moreover, 16S ribosomal RNA gene sequencing was used to profile the bacterial communities of the eggs and broodstock water from three commercial hatcheries. Proteobacteria were the most common and dominant phyla across the samples (49.7% on average). Vibrio sp. was the most highly represented genus (7.1%), followed by Glaciecola (4.8%), Pseudoalteromonas (4.4%), and Colwellia (4.2%), in eggs and water across the sites. Routinely used iodine-based disinfectants slightly reduced the eggs' bacterial load but did not significantly change their composition. Site, species, and type of sample (eggs or water) drove the microbial community structure and influenced microbiome functional profiles. The egg and seawater microbiome composition differed in abundance but shared similar functional profiles. The strong impact of site and species on egg bacterial communities indicates that disease management needs to be site-specific and highlights the need for species- and site-specific optimization of disinfection protocols.

Transcriptomic response of skeletal muscle to lipopolysaccharide in the gilthead seabream (Sparus aurata)

Project description:The physiological consequences of an activation of the immune system in fish are not well understood. In particular, skeletal muscle, due to its essential role in locomotion and whole-animal energy homeostasis, is a potentially important target of inflammation. In this study, we have evaluated the in vivo effects of lipopolysaccharide (LPS) on the white and red skeletal muscle transcriptome of the gilthead seabream (Sparus aurata) by microarray analysis at 24 and 72 hours after injection. In white muscle, the transcriptomic response was characterized by an up-regulation of genes involved in carbohydrate catabolism and protein synthesis at 24 hours and a complete reversal of this pattern at 72 hours. In red muscle, an up-regulation of genes involved in carbohydrate catabolism and protein synthesis was observed only at 72 hours after LPS administration. Interestingly, both white and red muscles showed a similar consistent down-regulation of immune genes at 72 hours post-injection. However, genes involved in muscle contraction showed a general up-regulation in response to LPS in both types of muscle. In summary, LPS administration causes muscle type-specific responses regarding the expression of genes involved in carbohydrate and protein metabolism and a common decreased expression of immune genes in skeletal muscle, concomitant with increased expression of genes for contractile elements. Our results evidence a robust and tissue-specific transcriptomic response of the skeletal muscle to an acute inflammatory challenge.

The Bromodomain testis-specific gene (Brdt) characterization and expression in gilthead seabream, Sparus aurata, and European seabass, Dicentrarchus labrax.

Project description:Multiple genes and transcription factors are involved in regulation and control of the complex process of sex determination and differentiation of fish species. Also more, several hormonal factors and some environmental conditions can also be adequate spawning strategies and stimuli for inducing reproduction of fish species. Brdt gene belongs to the bromodomain-extraterminal domain (BET) family of transcriptional coregulators. In mammals, Brdt gene is almost exclusively expressed in testis. Furthermore, Brdt protein is involved in elongating spermatids, and is required for proper spermatogenesis and male fertility. However, from our understanding of fish species, the role of this gene as key, during gametogenesis, still remains unknown. In this study, two Brdt mRNA transcripts were isolated from two teleostean fish species, gilthead seabream and European seabass. In both species the shorter form lacked a functional C-terminal domain, which may involve a different function as transcriptional regulator. The pattern of Brdt expression showed that the highest levels occurred in the gonads. Significantly lower levels of expression were detected in brain, pituitary and different organ systems (heart, kidney, gills, among other somatic tissues) from both studied species. In situ hybridization approach evidenced that Brdt mRNA expression was restricted to specific cell-types of the germ line, during both oogenesis and spermatogenesis processes.
